Double black (extreme) Breckenridge, CO
subline drops 564 vertical feet over 1,262 feet of skiing, with a steepest pitch of 37° about 70 feet below the top. That's steeper than 53% of the 2,251 double black runs we've measured in North America, and the 45th steepest of 207 named runs at Breckenridge. It faces east.
Facing east at an average 27°, subline gets about 112% of the winter sun that flat ground at Breckenridge does, December through March. That's sunnier than 82% of the runs we've measured, and the 35th sunniest named run at Breckenridge. Its top sits at 12,470 feet.
Angled toward the low winter sun, it bakes: powder turns heavy soon after a storm, and in spring it softens early in the day and refreezes hard overnight. Shading from ridges and trees isn't counted yet.
